The PPVT has been used as a screening instrument for evaluating potentially gifted students. It was recently replaced by the PPVT-R. The present study investigated the comparability of the two tests and of Forms L and M of the PPVT-R for 36 gifted students. All validity and reliability indices were statistically significant and ranged from .57 to .75. When means of various forms were compared the F ratio was significant, but the Newman-Keuls post hoc procedure identified only one statistically significant contrast, namely, the mean PPVT IQ was significantly higher than the mean PPVT-R, Form L, standard score.
